My understanding concerning black holes is this: If there is enough mass (which means quite alot, in this case) with only very little extension, i.e. lots of mass in a tiny little region of spacetime, spacetime will curve according to this and eventually (the event being: enough mass) form a black hole, from which there is no way out. Absolutely no way out, not even for light. (I'm not talking about quantum fluctuations at the "border" of a black hole, here.) My point is: once you're inside, you can't get out.

Now the standard Big Bang theory, as far as I understand, says that at the very beginning all mass of the entire universe was at one point, from which it expanded: it made bang. But: How could that possibly happen? All the mass of the entire universe is certainly enough for a black hole to form, the spacetime region certainly small enough. Why didn't the whole thing collapse into a black hole instead of expanding all the way?

Thanks alot for any explanations. Best regards...Cliowa
